Tbh a hover is not useful. I'm not going to hover over stats while my stream is live. I need to see the number at a glance, not alt-tab, move mouse, look at number, alt-tab back in.

totally understood. We have a lot of data to suggest that most people don't have this window open when live, many people have the stats tab collapsed, etc.
There are ways we could explore this, the majority of streams I see that engage in goals related to staff typically have it in their streams and therefore in their stream previews as well.
